Technical Summary & Usage

Space Gray Marble exhibits high density and low porosity, making it an excellent candidate for both interior and exterior applications. Its compressive strength remains robust even after freeze-thaw cycles, which is critical for exterior cladding in varied climates.

  • Primary Uses: Interior flooring, wall cladding, luxury countertops, and bathroom vanities.
  • Recommended Finishes: Polished (to enhance depth), Honed (for a contemporary matte look), or Sandblasted (for slip resistance in wet areas).
  • Maintenance: Due to its calcium carbonate structure, it is recommended to seal the surface to protect against acidic substances and heavy staining.
